The young fans were reportedly watching an Asian Cup match between Iraq and Jordan on TV last week when they were caught by the militants in the Iraqi city of Mosul, which ISIS, or the Islamic State, controls.

The group of teens was executed in public by a firing squad that used machine guns, according to Raqqa Is Being Slaughtered Silently, an activist group that exposes ISIS atrocities.

Before the kids were killed, their “crime” was announced over a loudspeaker, reports said.

“The bodies remained lying in the open and their parents were unable to withdraw them for fear of murder by the terrorist organization,” RIBSS posted on its website.

The boys were slaughtered because they were said to be violating Sharia law by watching the game.

Iraq beat Jordan 1-0 in the Jan. 12 match, which took place in Brisbane, Australia.

A few days earlier, the Islamic State released a gruesome video showing two men being flung off a tower in Mosul.

Before the execution, a masked fighter using a hand-held radio announced to a crowd of onlookers that the condemned duo had been found guilty of engaging in homosexual activities.

Meanwhile, the Islamic State is winning the war against heavy winter storms battering Iraq and Syria, huge swaths of which they control.

US military officials told The Post the terrorists are completely unfazed by brutal weather conditions that have plagued Syrian and Iraqi refugees currently being helped by the United Nations.

“[ISIS] is a well-funded group, able to purchase cold-weather equipment,” said one US military official.

“Also, while there are some foreign fighters, the vast majority of [ISIS] are from the area, so they know how to adjust for weather conditions,” the official added.
